SPECIFICATION forming part of Letters Patent N0. 395,132, dated December 25, 1888.

Application filed October 23,1385. Serial Not 180,704. (No model.)

To all 1./:7t071t it 71mg/ concer/L.-

Beit known that I, DAVID F. lrRAHAM, a citizen of the United States, and a resident of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Horse Hay-Rakes, of which the following is a specifi cation.

My invent-ion relates to improvements in vhorse hay-rakes; and the objects of my improvements are, first, to so construct a horse hay-rake as to effectively gather the hay into the form of windrows; second, to so construct said rake as to produce a continuous and easy draft by obviating the necessity of dumping the hay at intervals, as is usually done, and at the same time to produce a clean, narrow, and even windrow. These objects l accomplish in the manner illustrated in the accompanying drawings, in which- Figure l is a plan view of my improved rake with a portion of the mechanism removed from one of the raking-frames. Fig. 11L is a plan view, on a larger scale, of the parts uniting the arms 715 of the frame to the shafts c of the machine. Fig. 2 is a side elevation of Fig. l. Fig. b is aperspective view of the lower end of one of the tooth-carrying slats, showing a portion of the tooth in position for raking. Fig. Je is asimilar view showing the tooth-block head and tooth released from the flanged track and partly turned out of raking position. Figs. 5 and ti are front and side views of the slats and tooth-block head. Fig. 7 is a side view of the frame used to support each rake.

Similar letters referto simila r parts throughout the several views.

The carriage or frame-work of my improved rake is constructed in the usual manner, consisting of the wheels a, mounted on the axle d, carrying the shafts c. (Shown broken away.) Said shafts are united by the transverse bar c2. On the axle c7, between the shafts c and the wheels o, are loosely pivoted metal lugs L b', to which are bolted the rear ends of arms t? b and 715 b5, which project forwardlyto points beyond the front of the wheels. Each of the arms b5 b5 is bolted at its outer end to one of the outer sides and near the center of a vertical angle-iron, y, the arms l) 7J being bolted to points near the tops of said angle-irons. To each of these angle-irons, near the middle of its length, is also bolted a bar, 71. bars 7i extend outwardly from the sides of the frame in a forwardiy-oblique line, the inner or rear ends projecting slightly within the inner line of the shafts c. To the lower end of each of said angle-irons is similarly secured a bar, 7L', parallel with the bar 7i. A further connection is made between the bars 72 7L by means of wooden stays or braces t', which are bolted at their lower ends to points near the outer ends of the lower bars, 7L, and near the center of their length to the upper bar, 7:, their upper ends being' bolted to the top portions of the angle-ironsI y. Running from the outer ends of the axle (I and loosely pivoted thereto are braces e, which, extending forwardly and outwardly, are bolted at their extremities to the bars 71.

On the axle (7, between the arms lf and the wheels @,are fixed sprocket-wheels ef. Each of these sprocket-wheels, by means of a suitable chain belt, n, communicates motion to a smaller sprocket-wheel, a1, fixed on the end of a short shaft, fr', which, resting` in bearings in the outer end of the arm b5, projects inwardly and passes through a lug, h2, made to project from the bar 7L, and carries on its inner end a small beveled cog-wheel which engages with the cogs on the lower side of a beveled gearwheel, if, fixed on the upper end of avertical shaft, 'o'. These shafts o', which have their lower bearings in the bearings 7o in the lower bars, 77X, and their upper bearings in the bearings 7t' in the upper bars, 71, carry sprocketw reels fw w', fixed, respectively, at points immediately above and immediately below the lower bars, 71', and the upperbars, 7L. Between the outer ends of each pair of bars 71 7L is loosely pivoted in bearings 7c, secured to said bar, avertical shaft, o?, each of these shafts o2 carrying sprocket-wheels 102 and w3, corresponding in position and size to the sprocketwheels w and w. These sprocket-wheels w w and 102 w3 are adapted to carry continuous chain belts 0 o', having alternately open and solid links. To the outer sides of the solid links in each of these chain belts o are bolted or riveted the upper ends of vertical slats m, which, extending downward, are similarly secured a short distance above their lower ends to corresponding links in the belts o. To the outer side of each of these slats m, (or to each These IOC alternate slat,) near its lower, end is bolted the upper end oi' a metal casting, r. Said casting, extending downward below the end of the slat, is provided with a downwardly-projecting pin, r3, on which is loosely pi voted the head of an oblong block, s, said block also carrying a transverse pin, s', fixed between two outwaifdly-proj ecting arms, 32, on the head of the block, on which pin is wound the upper end o t' a downwardly-projecting curved metal tooth, t. The block s is retained upon the pin r3 by means of a key, r4, passing through said pin under said block. linmediately beneath the lower ends ot' each of the series of slats m is placed an endless metal track, f, of angle-iron, having its outer edge vflanged upward and its inner edge about onehalf its length flanged downward at j to give a part rotation to the cam-block. rlhis metal track is held in its proper place by means of metal braces l, bolted to the inner flanged side, f', of the track and to the lower bar, h. Projecting inwardly from each of the castings r, and bearing against the bottom of each of the slats m is, a lug, r', which, projecting over the top of the track f, has near its outer end a downwardly-projecting pin, r2, on which is loosely mounted a small guide-wheel, u, which is adapted to run against the inner side of the outer flange of the track.

Motion having been communicated to the shaft v', as above described, it is thus transmitted to the sprocketwheels w rr, and thence, through the chain belting 0 0', having the slats m secured thereto, to the sprocketwheels @U2 and yw3 and shafts The motion thus given to the slats m operates to carry the castings r along the track f and cause the teeth t to move forward. The inner flange,

f, of the track extends only around the i'or ward or front half oi the tracks and is cut away at the point A and continued again at the point A. The rakes being set in motion, as above described, the curved feeth are kept pointing forward in a position io gather the hay by means of the blocks s, which are held in place by their pressure against the outer side of: the flange f ot the track j', as shown in Fig. S of the drawings. 'When the point A at the inner end of the track is reached, the block .s is allowed to escape its bearing against the flange j", and, by pressure of the hay against the tooth, is swung' to the rear, thus reversing the tooth, throwing its curved end out of position for raking, as shown in Fig. @L of the drawings, and allowing the hay which it may have gathered to be deposited at that point. lVhen the point A is reached, the block again coming in contact with the ilange f', it causes the tooth to again assume a raking position. ln order to prevent the pressure of the hay against the tooth from pulling the casting away from the track, I provide the guide-pulley u, before described. The raking devices above described are supported and kept at their proper height above the ground by means o'f caster-wheels 2J, pivoted to the lower ends ot' metal arms p', which project from the lower side of the lower bars, 71. The lugs ZJ', being hinged or loosely pivoted to the axle cf, admit ofithe rising and vfia-lling of the arms if b as the caster-wheels y) come in contact with high or low ground. ln order to produce an easy motion of' these parts and to prevent the arms b5 from being pulled outward, l secure, by bolts or otherwise, at convenient points on each of the arms b5, an inwardly-projecting lug, b2, on which is loosely mounted a small guide-wheel, b", which is adapted to bear and run against the inner side ot' the iianged edge of a metal plate, b3, made to project outwardly lf "rom the shaft c.

3y the construction and operation of' the apparatus herein describei'l, it will readily be seen that the hay within a certain distance Vfirom each side ol' the running-gear will be raked in and deposited in the 'fform of neat and even windrows between the wheels of the carriage, and that an easy and steady draft is obtained by thus obviating the necessity oi` dumping the hay at intervals.

Having now fully described my invention, what l claim, and desire to secure by Letters Patent, is

l: A series of raking-teethcarried on either side of:l the running-gear of' a horse hay-rake by blocks s, secured to the castings r, bolted to the vertical slats 1n, said slats being carried by means of' endless chain belts o o', sprocket-wheels 'uf zu u'2 1r, fixed ou shafts r r2, having bearings iu the bars 7L 71.1', beveled gear-wheels r, small beveled cog-wheels fixed on the ends of short shafts a, havingbearings in the bar-lugs h2, and the arms b5, pivoted to the carriage-axle and carrying small sprock et-wheels .r, operai ed by the endless chains n from the sprocket-wheels c', mounted on the carriage-axle (if, substantially as and for the purpose specified.

2. 'lhe combination of:l the gi'mnld-n'lleels n, their axle, the arms b, the vertical angleirons y, and `bars 7i., having a journal bea-ring at each end, with the endless metal track j', having a downward flange Yfor half of ifs length, and an endless chain having vertical slats m, pivotally-reta-ined blocks s at the lower ends thereof, and spring-fingers t, sub stantially as and for the purpose described.

i). The combination off the ground-wheels, axle, sprocket-wheels, and chains n with shafts carrying sprocket-wheels w w', an endless chain, its vertical slats m., having castings r and Vfi'ricfiion-rollers u at the lower IOO IIO
